Golf Ball and Silk Vase

A vase is opened, and a white handkerchief removed from inside. The handkerchief is magically "rolled" into a solid ball. The ball is placed in your pocket, and reappears inside the vase. The vase is tapped, and the ball magically penetrates right through the vase. Finally the ball vanishes, and the original silk is found again in the vase. Supplied plastic vase and golf balls, 2 silks and full routine.
